Details:

Maschine: Intel Core 2 Duo E6600 2.00GB RAM
XP Professional Sp3
Cygwin 1.7.8-1
Octave 3.4
Gnuplot 4.4

The first row will not be drawed!
(possibly a problem of floating point condition?)

x = [10:2:30];
y = [7.1:0.1:7.5];
z = [1:11;2:12;3:13;4:14;5:15];
surf (x,y,z)
-> Plot missing: y = 7.1

x = [11:1:14];
y = [7.1:0.1:7.3];
z = [1:4;2:5;3:6];
surf (x,y,z)
-> Plot missing y = 7.1

x = [11:1:14];
y = [7.2:0.1:7.4];
z = [1:4;2:5;3:6];
surf (x,y,z)
-> Plot  y = 7.2 exist
The first row is drawed!

----------------------------------
the same with:

Linux Debian 5.0 Kernel 2.6.26 
(Lenny live)
gnuplot_4.2.2-1.2
octave 3.0.1:3.0.1-6lenny3

x = [10:2:30];
y = [7.1:0.1:7.5]
z = [1:11;2:12:3:13;4:14;5:15];
surf (x,y,z)
-> Plot missing: y = 7.1

x = [11:1:14];
y = [7.1:0.1:7.3];
z = [1:4;2:5;3:6];
surf (x,y,z)
-> Plot missing y = 7.1

x = [11:1:14];
y = [7.2:0.1:7.4];
z = [1:4;2:5;3:6];
surf (x,y,z)
-> Plot  y = 7.2 exist
